The controller includes an electronic processor and a memory. The controller is configured to receive one or more signal from the one or more sensors corresponding to the one or more characteristics, and control the fuel injector based on the one or more signals.

A burner includes a flame sensor configured to detect at least one of permittivity, capacitance, or resistance across a flame region. The permittivity, capacitance, or resistance is used to determine the presence or absence of the flame in a combustion system. A combustion system supports a combustion reaction. The combustion system utilizes a combustion sensor, and optionally a plasma generator to stabilize the combustion reaction. A controller receives sensor signals from the combustion sensor and controls the plasma generator to stabilize the combustion reaction responsive to the sensor signals. The plasma generator stabilizes the combustion reaction by generating a plasma.

The present disclosure deals with the measurement of flows of a fluid in a combustion device. For example, a combustion device may include a burner; a combustion chamber; a side duct; and a feed duct with a connector for the side duct including a mass flow sensor and a flow resistance element. The side duct and the feed duct have a fluid connection to one another. The mass flow sensor senses a mass flow through the side duct. The resistance element subdivides the side duct and includes an admittance surface. There is an outer area. The mass flow sensor projects into the side duct. The outlet of the side duct lets the fluid flow out of the side duct directly into the combustion chamber or directly into the outer area.

The present disclosure deals with the measurement of flows of a fluid in a combustion device. In particular embodiments, the teachings may be employed in the measurement of flows of fluids such as air in the presence of turbulence. For example, a combustion device may include: a burner; a side duct; and a feed duct. The side duct may include a mass flow sensor and a flow resistance element. The mass flow sensor detects a mass flow through the side duct. The flow resistance element subdivides the side duct. A connector of the feed duct comprises a Pitot probe. A first section of the Pitot probe projects into the feed duct and a sub area facing towards the outlet of the feed duct of the first section of the Pitot probe comprises the inlet of the Pitot probe.

A device for mixing combustible gas and combustion air, hot water installation, and corresponding thermal mass flow sensor and method. The device includes an air line, a gas line with a control valve, a first measuring line connecting the air and gas lines, and a second measuring line connecting the first measuring line to the gas and/or air line, forming a three-way intersection. A thermal mass flow sensor includes first and second temperature sensors in the first measuring line, positioned respectively in a gas flow between the three-way intersection and the air line and in a gas flow between the three-way intersection and the gas line. A controller controls the control valve based on a difference, measured by the flow sensor, between mass flow rate of gas between the three-way intersection and the air line and mass flow rate of gas between the three-way intersection and the gas line.
